Question of the Week: which concept car would you most like to see brought to life?

Concept cars are brilliant, wouldn’t you agree? They often demonstrate a combination of manufacturers’ ambition and designers’ unshackled possibilities, but the sad reality is too few make it to production.

Take our coverage last week of the Honda HP-X. Created during the Eighties as a preview for what a then-futuristic Honda performance vehicle could be, it’s mid-engined, has an incredible amount of tech and, even now, looks like it would fit in a world built by Skynet. Though it would later inspire the development of the NSX, it too never saw the showroom floors.

It got us thinking: which are the greatest concepts that never made it any further? We’ll shine some light on a few of our personal favourites.

Remember the Cadillac Cien? Built to commemorate the marque’s 100th anniversary, it was all set to be the car which revolutionised Caddy's image with a massive 7.5-litre ‘Northstar’ V12 and striking looks.

Or how about the 16C Galibier from 2009? Though mostly associated with low-slung, two-door, million-horsepower hypercars, Bugatti did once conceive the idea of extra doors and a much longer body. It also teased how not to style a saloon’s grille before BMW came and took that idea to another level entirely.

One more: remember the Mazda Furai? Based on an LMP2 racer, it was designed as a two-door, tri-rotor screamer that could’ve been the road-going successor to the legendary 787B. Let's quickly gloss over its unfortunate demise.

Anyway, over to you lovely people: which concept takes your vote? As per usual, the very best comments will form the structure of our Friday round-up post. Happy posting.
